To use edX course content in the Canvas LMS, you add a new app to the course and then add external tool module items.

Note

This example relies on the use of a third-party tool. Because this
tool is subject to change by its owner, the steps and illustrations provided
here are intended as guidelines and not as exact procedures.

In Canvas, select your course. In Settings, select Add New App.

In Modules, add a new External Tool item. The URL is the LTI
URL that you determined for the edX course content, such as
https://edx-lti.org/lti_provider/courses/course-v1:edX+DemoX+2014/block-v1:edX+DemoX+Demo_Course+type@problem+block@d2e35c1d294b4ba0b3b1048615605d2a.
